IR Thermal Imaging

Infra-Red Thermal Imaging is a useful tool in regular use at ARA. It is commonly used to analyse the efficiency and performance of the large motors that serve the Transonic Wind Tunnel (TWT) and is increasingly being used during model tests in the TWT to gather data on the surface temperature of the models under test. One recent example was the use of this technology alongside Temperature-Sensitive Paint (TSP) to visualise surface flow features.
